उत्पद्यन्ते तदा ते वै सम्प्राप्ते तु कलौ युगे अधीयन्ते तदा वेदाञ् शूद्रा धर्मार्थकोविदाः
utpadyante tadā te vai samprāpte tu kalau yuge adhīyante tadā vedāñ śūdrā dharmārthakovidāḥ
When the age of Kali has fully arrived, they indeed arise—Śūdras who study the Vedas and become skilled in the aims of dharma and artha.
Suta Goswami (narrating to the sages of Naimisharanya)
It frames Kali-yuga as an age of social and religious inversion; in such instability, the Linga becomes a direct, accessible focus for devotion to Pati (Śiva) beyond fluctuating external qualifications.
Indirectly: by highlighting changing worldly structures (varna-based access and authority), it implies Śiva as Pati—the stable transcendental ground—while dharma in the world becomes variable in Kali-yuga.
No specific rite is named; the takeaway is that in Kali-yuga, disciplined sādhana (such as Śiva-bhakti centered on the Linga and Pāśupata-oriented self-restraint) becomes crucial amid shifting norms.
